I've been playing Marvel Heroes Massively Multiplayer Online Game this past week.

It is free to play, but like many of these online-only games, you'll
need to pay if you want different costumes or additional characters.
Gameplay is like a 3-D version of Diablo, only with Marvel characters.
You can test it out for yourself at marvelheroes.com

I looked around their store, they offer a Scarlet Witch "Romani"
Costume, is based on George Perez's redesign of her costume in 1998. As
noted on Marvel Heroes' website:

COSTUME HISTORY
Avengers #8 Vol 3 (Sept. 1998)

Not long after rejoining the Avengers, Wanda redesigned her costume in
order to get in touch with her Gypsy heritage, which she would wear for a
few years before returning to her Classic costume.

The Romani costume costs 950 G which translate to slightly less than $10 ($1 is about 100 points).
